The Folk Box
The Folk Box was released by Elektra Records in 1964 and consisted of four LP's with each side featuring a particular style of Folk or Traditional music. From what I read, this was an excellent collection. Since this ad was ran seven years after its release, it was most likely a way to unload unsold copies. For those interested, listed below are the styles of folk music featured in each LP side.
Side 1: Songs of the Old World and Migration to the New
Side 2: Settling, Exploring and Growing in the New World
Side 3: Work Song
Side 4: Many Worshippers, One God
Side 5: Country Music - From Ballads to Bluegrass
Side 6: Nothing But The Blues
Side 7: Of War, Love and Hope
Side 8: Broadsides, Topical Songs, Protest Songs
